From “The Eighteenth Canto” by Jadhrumelarin Ix

Canto XVIII(Retranslated from High Arakeus by Cantor Simuhideen Jox in 137 PCA)
The Light, having set itself upon the world in finite amount, shall recede with the passing of ages. And when the light is so far gone as to be only a speck in the darkness or less, a new Light will burst upon the dark world, bringing with it a new order. Those who aided will be set upon thrones of light, and the task given unto them will be the remaking of the cold stone that is our world.

Commentary(Written by Arch-Cantor Jadhrumelarin Ix in 589 PCA)
Canto XVIII is the most controversial part of the Hymn, and more of the Concordance is given over to it than to any other of the other eighteen cantos. This is because the ambiguity of the phrase “those who aided” (udunaal in High Arakeus);it is unclear if this refers to people adding others, aiding the Light in persisting, or aiding in snuffing it out and bringing darkness.

The result is that many cults and revival movements have seized on Canto XVIII as the basis for their deviant beliefs. They tend to fall into two camps. The first, “Kindler” cults, believes that by increasing the amount of light in the world, they will be rewarded when the light eventually fades. They are notorious for their acts of arson and self-immolation.

A second, and perhaps more dangerous grouping are the myriad “Dusker” cults. They hold that extinguishing light will bring about the end of the Universal Lightmore quickly, and that by helping to extinguish this “imperfect light” they will be rewarded in the soon-to-come. Duskers were responsible for the shattering of five of the seven Sunstones, for instance, helping to bring about the Dark Age.

“Kindlers” tend to be short-lived cults, as arson and immolationtend to, if one will pardon the pun, burn themselves out before long. “Duskers” on the other hand tend to be larger, better-organized, and far more dangerous. Both, however, are equally heretical.
